Vocal Cords> You probably talk, and you might even sing. Have you ever thought about how you make these sounds? The vocal cords are an important part of the production of the human voice. Here are a few things about this amazing instrument.
The human voice is produced in a section of the throat called the <#5658,5111><!larynx>. Two small folds of tissue stretch across the larynx. These folds, called vocal cords, have a slit-like opening between them. When you speak, muscles in the larynx tighten the vocal cords, narrowing the opening. Air from the lungs rushes past the tightened cords, causing them to vibrate.
The <#5679,2><!vibrations> produce the sound of the voice. Tighter vocal cords vibrate more rapidly and make higher frequency sounds; relaxed vocal cords vibrate more slowly and make lower frequency sounds. The more air you send past your vocal cords at once, the higher the amplitude of the sound will be - to shout, you really have to push a lot of air past those vocal cords!
